NON-REFILLAIBLE BOTTLE.

Specification of `Letters Yatent.

Application filed December 11, 1913.

To all whom it may concern:

Be it known that I, WILLIAIWI W. SMITH, a citizen of the United States, and a resident of Darlington, in the county of Harford and State of Maryland, have made certain new and useful Improvements in Non-Refillable Bottles, of which the following is a specification. n

My inventio-n relates to improvements in iion-reiillable bottles, and it consists in the combinations, constructions, and arrange ments herein described and claimed.

An object of my invention is to provide a receptacle for holding liquids from which the liquids may be readily poured, but into which the liquids cannot be readily returned after it is once emptied.

A further object of my invention is'to provide a device of the type described which is of a relatively simple nature and therefore is cheap to manufacture.

Other objects and advantages will appear in the following specification and the novel features of the device will be particularly pointed out in the appended claim.

My invention is illustrated in the accompanying drawings forming part of this application in which- Figure 1 is a section through the neck of the bottle or receptacle showing the latter in its normally closed condition, and Fig. 2 is a similar section showing the bottle tipped to permit the emptying of the contents thereof. Fig. 3 is a plan view of the bottle closure.

In carrying out my invention I make use of a receptacle of any suitable shape or material. In the present instance I have shown the receptacle as consisting of a bottle h aving a body portion 1 at the top of which is a neck formed like that shown in Fig. 1. It will be seen that the neck is constricted at a point 2 just above where it joins the body portion. From this point it tapers outwardly to a point 3. The portion between the point 3 and the point l is substantially cylindrical. A shoulder 5 is disposed on the inner side of the neck at this point, while above the shoulder 5 is a shoulder 6. The latter is formed by curving the sides of the bottle so as to form a bead 6X on the outside' thereof which adds to the appearance of the bottle, and at the same time makes it stronger. From the shoulder 6 to the bead 6x the neck is fashioned on a double curve as clearly shown in Fig. 1, while between the point 7 and the top of the bottle S the inner portion of the neck is tapered so as to hold the cork 9 securely.

The closure for the bottle consists preferably of an impervious body portion 10 which is preferably of porcelain, and which is tapered in the manner shown in Fig. 1. It is held in a metal ring 11 which has a series of outwardly bent spring fingers 12 made integral with the ring, and a series of inwardly bent spring fingers 13 also integral with the ring and shorter than the fingers 12.

From the foregoing description of the various parts of the device the operation thereof may be readily understood.

The closure 10 is designed to fit tightly within the ring 1]., but in order to prevent it from slipping out therefrom the spring fingers 13 are bent inwardly, as shown. The bottle or receptacle is iilled in the ordinary manner and when filled the closure is thrust through the upper end and forced downwardly by means of a stick or other convenient tool, the spring fingers 12 bending inwardly until the lower portion of the neck is reached when the closure 10 will enter the constricted portion 2, thereby effectually stopping up the latter. The bottom portion of the neck is wide enough so that the spring lingers 12 exert little or no tension on the sides of the neck.

Now when it is desired to pour out the contents of the bottle it is tipped in the manner shown in Fig. 3, when the closure 10 will fall away from the opening at 2, thus permitting the liquid to pass by the closure and by the spring lingers and out through the mouth of the bottle. It will be observed that the shoulders 5 prevent the passage of the closure out of the bottle. If during the movement of the closure the spring fingers 12 on one side should happen to pass the shoulder 5 they will be stopped by the shoulder 6, which, it will be observed, extends farther in toward the center of the neck. Any attempt to force liquid into the bottle will result in forcing the closure into the constricted portion 2, thereby eft'ectually sealing the bottle. Under certain conditions small portions of liquid may be forced past the closure, but not enough of the liquid can be forced past in Order to make cominercial use of the bottle for purposes of again dispensing liquid therefrom. The debody portion, and integral spring fingers i5 carried by said metal ring, certain of said spring fingers being bent inwardly toward one another and other of said spring fingers being bent outwardly, said outwardly bent spring fingers being` arranged to engage 20 Said shoulder for preventing the dislodgrnent of the closure from the neck of the bottle.

WILLIAM VADE SMITH.
